Base62 Encoding: One particular widespread solution is to use Base62 encoding (which utilizes 62 figures: 0-9, A-Z, and also a-z) on an integer ID. The ID corresponds into the entry in the database. This method makes sure that the shorter URL is as shorter as possible.
Random String Technology: Another strategy is always to deliver a random string of a fixed length (e.g., six characters) and Examine if it’s previously in use from the databases. If not, it’s assigned for the very long URL.
